Abstract:The thermal conductivity of stainless-steelmaking dust pellets, an important parameter for the direct recycling of the dust, is naturally of interest to metallurgists. The measurement of central temperature and surface temperature was taken in a furnace. The physical model and calculation model for the heating process were set up to check the thermal conductivity of the dust pellets. The physical structure parametersδandλof the basic unit are 0.92 and 0.45 based on the calculation. The temperature in the pellet can be expressed in a linear equationa5TP=a1TN+a2TM+a4. This is convenient to determine the central temperature of a pellet in the direct recycling process.
Key words: thermal conduction; stainless-steelmaking dust; recycling
